Which of the following reagent(s) used for the conversion? [Starting compound: CH3COCH2CH2CO2Et] [Product: CH3COCH2CH2CH2OH]

1. glycol/LiAlH4/H3O+
2. glycol/ NaH/H3O+
3. LiAlH4
4. NaBH4

Correct answer: glycol/LiAlH4/H3O+

Solution

The correct option involves glycol and LiAlH4, which together facilitate the reduction of the carboxylic acid derivative to an alcohol, while the H3O+ helps in protonation, ensuring the conversion to the desired product.
